Abstract:The key of seismic data processing mainly lies in static corrections and imaging and both of them are relative to velocity model in complex near-surface and underground geologic structural conditions.The paper analyzed the influence of surface model,near-surface model and interval velocity model on static corrections and imaging,studied mutual relation among static corrections and imaging as well as interval velocity model in the procedure of data processing,presented the realized methods of prestack depth migration when the velocity model included surface elevation and near-surface model and reasonably solved the combined influence of surface elevation,surface weathered layer and near-surface layers on static corrections and seismic imaging,which achieved good applied results.
